AT&T will finally be lifting its almost 3-year ban on FaceTime (and other pre-installed video chat services like Google Hangouts on ANdroid) for its customers on grandfathered unlimited data plans. Over time, AT&T has made stock video chat apps available on its cellular network only to customers on tiered data plans, or its newer Mobile Share plans, while unlimited users looked on in disappointment. That all changes starting next month, when customers with LTE devices get access to pre-installed video chat services:

For video chat apps that come pre-loaded on devices, we currently give all OS and device makers the ability for those apps to work over cellular for our customers who are on Mobile Share or Tiered plans. Apple, Samsung and BlackBerry have chosen to enable this for their pre-loaded video chat apps. And by mid-June, we’ll have enabled those apps over cellular for our unlimited plan customers who have LTE devices from those three manufacturers.

So if you've got an iPhone 5, you're in luck. If you are on an older iPhone 4S or iPhone 4, you have a bit more of a wait ahead of you. In fact, it appears that even if you have a current LTE device that isn't made by Apple, BlackBerry, or Samsung, you've got a wait ahead of you. Recent buyer of the awesome HTC One? Sorry:

Throughout the second half of this year, we plan to enable pre-loaded video chat apps over cellular for all our customers, regardless of data plan or device; that work is expected to be complete by year end.

We've been getting reports that some AT&T customers with unlimited plans and LTE devices are already seeing FaceTime over Cellular enabled.
